COMBINED RAILWAY-TRACK GAGE AND LEVEL.

SPECIFICATION forming part of Letters Patent No. 331,329, dated December 1, 1885.

' Application filed May 12, 1885. Serial No. 165,188. (No model.)

To all whom it may concern:

Be it known that I, DANIEL H. BHoDEs, a citizen of the United States, residing in the city of Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Improvement in Combined Railway Track Gages and Levels and Standards for Testing Track-Gages, of which the following is a specification;

My invention is illustrated in the following drawings, in which Figure 1 is a plan of my improvement with a portion, whose form is evident, broken out from the center for want of space within the margin. Fig. 2 is a side elevation with a similar portion broken out as in Fig. 1. Fig. 3 is an end elevationof a portion of Fig. 2 at the left of a vertical section made in the line in in; and Fig. 4 is an end elevation of a portion of Fig. 2 at the right of a vertical section made in the liuenn.

My device consists, essentially, of a round or polygonal metal rod, A, of about a half inch in diameter and from five to six feet in length. At one end a T, O, is forged to the rod, and near the other end, at its under side, an adjustable shoulder, B, is fitted to the rod. This shoulder, at its face, is in the form of a cross, Fig. 4, the foot being attached to a slide whose upper surface is shaped to con form to the undersurface of the rod. A thumbscrew, 00, playing in a slot in this slide and screwing into the rod, holds the slide and its shoulder B in its desired place against the rod. By this means the shoulder may be similarly adjusted to other points upon the rod within assigned limits, as at B. The scale D upon the slide is cooperative with the fixed line at on the rod, determining the number of feet and inches embraced between the face of the shoulder B and the crown face of the T O. The face of the shoulder and the crown-face of the T O are curved in construction to a radius whose length is the standard gage of the track. By placing the face of the. shoulder B against the inside of the head of one rail and then dropping the T G to a corresponding point of the opposite rail the gage of the track may be tested, and by the aid of the adjustable shoulder and its scale D the gage may be measured in feet and inches, the

upper side of the rod near the end terminating in the T O. This ledge is provided with steps 1', graduated to any desired scale. The base of the fluid-level H employed herewith. is fitted to conform to the upper side of the rod A. When the track is level and the rod in place, the bubble of the level will take the center when the level rests wholly on the rod. If, however, the track inclines from side to side, the step of the ledge I, upon which one end of the level must rest to bring the bubble to the center, will indicate the degree of the inclination of the track.

To provide a standard for testing the service-gages employed in the construction of the track and in its repairs, at crossbar, E, is fitted at right angles to a cap'bar, E, attachable to and removable from the upper side of the rod A, near to the end opposite the one terminating in the T. This crossbar E is held firmly in place on'the cap-bar E by the semicircle G, while the cap-bar is held securely against the rod by the thumb-screw 2. Two or more uprights or shouldersin the drawings three, e c 6', being shown-are forged to the crossbar E, their inner faces all being in the same plane perpendicular to the rod and at distances apart from each other corresponding to the similar distances apart of the similar shoulders of the service-gages to be tested. Another and adjustable shoulder, F, is secured to the same side of the rodA, near its opposite end, by means of the thumb-screw 3 This shoulder F may be adjusted to any desired point within given limits, as in case of the shoulder B, one such point being indicated by F. The service-gage to be tested is applied to this standard by placing the outer faces of its uprights or shoulders against the inner corresponding faces of the shoulders e e e and dropping the crown face of other end of the service-gage inside the shoulder F. Thus the reach of the service-gage may be determined in feet and iuches by the aid of the scale D steps 2', level H, removable bar E, with shoul- IO and its (Jo-operating fixed line cl impressed ders e e e, and adjustable shoulder F, with upon the side of the rod. scale D, all constructed, combined, and oper- Whal; Iclaim as my invention, and desire to alaiug substantially as and for the purpose secure by Letters Patent, is hereinbefore described.
